. 11 Claims. .This invention relates to a foot deodorant pad I and this application is in part a continuation of nent, even distribution our co-pending application Serial No. 14,552, filed April 4, 1935.

Persons troubled with perspiring feet under normal every day conditions 'and in spite of their efforts for personal hygiene, ndit embarrassing due to odors caused thereby. Itis therefore one of the principal objects of this invention to provide a pad for insertion into the shoe of a wearer which does not interfere with the natural sweating of the foot but absorbs perspiration therefrom and deodorizes the same to arrest any obnoxiousodors which ordinarily would emanate therefrom.

Another feature of the invention resides in an antiseptic foot deodorizer which includes a foot pad constructed of gossamer-like layers oi' 'cellulose material containing a deodorant substance having sublime characteristics so as to be eifective only whenthe body heatvand perspiration from the foot of a user renders the same chemically active to change the normalsolid state of the substance into a state of vapor. Thus the strength of the deodorant is ever present in the pad until use of the same and loss of the strength is avoided during intervals between use, for such sublime substances as we employ for deodorant purposes condense or return to their original or normal solid state in the absence ofheat.

A further feature of the invention is to provide in the pad body compressed portions which impart, first, strength to the pad structure; secondly, it fixes themedication to'insure its permaand prevents sifting'of the same: and thirdly, it eliminates buckling or shifting of the 'delicate foils lor gossamer like layers.

Another feature of -theinvention is the -provision of an antisepticvdeodorant foot pad which will not injure or irritate the foot of a user nor cause undue wear upon the stocking or sock, and will not impair the shape of the shoe.

A further feature of the invention resides in a hygienic deodorant foot pad which is absorbent and which in the presence of body heat and perspiration releases the deodorant, aromatic, and antiseptic vapors within the shoe of a user, and about the lfoot therein.

A still further object of the invention is the provision of a deodorant foot pad having the above features which is simple and inexpensive of manufacture to'enable retail sale at a price which will enable complete disposal of the article may'be employed if desired.

(ci. srs-44) after limited use without undue expense to the users thereof.

With these and other objects in view, the in Y vention resides in certain novel construction, combination and arrangement of parts, the es- 5 sential features of which are .hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which:

Referring to the drawing by reference characters, 'the numeral I0 designates our deodorant foot pad in its entirety which comprises broadly, a ilexible base II. a soft porous absorbent pad body I2 impregnated with a deodorant, antiseptic, and aromaticsubstance, and a fabric covering I 3. IQlhe base II is of a-shape corresponding to that of the sole of a shoe, into which the article is adapted to be inserted for use, the edges of the pad body I2 following the curvatures oi?l the base Il. It will be understood that the articles will be constructed in "right and left to be sold in pairs, andthey will also be made in different sizes to dt into` different sized shoes.

The base I I may be constructed of any suitable thin ilexible material such as cardboard sized on the underside, although any equivalent. thereof the deodorant The pad body I2 is composed of creped or uncreped sheeted cellulose wadding. This wadding is constructed of a plurality of gossamer thin sheets, plies, layers, foils, laminae, or the like I4, of pulped cellulose fibers. 'I'hese pulped cellulose fibres are obtained' from disintegrated wood, rags, grass, or other vegetable matter. 'I'he nucleated 'andconnective fibers of each gossamer thin sheet are so arranged as to create a close, consistent tenuous feltwork, web-like construction or felted sheet of homogeneous fibers that are highlyeabsorbent.

The blank of cellulose wadding from which the pad I2 is die cut, is'treated with a deodorant sublime substance by inserting such substance between certain of the gossamer like sheets I4.

'Such deodorant substance may either bersprayed onto the layers I4 or if the'substance is of a solid powdered form, the same may be sprinkled between the layers as shown in Figure 6 of the drawing. Whereas various medicaments may be employed as the sublime deodorant, we have found that excellent results occur by the use of paraformaldehyde or trioxymethylene for the reason that this chemical not only deodorizes the perspiration but prevents and destroys rancidity and decomposes the deposits of fat, salt, urea, etc., which are present in sweat and which cause the obnoxious odors. When paraformaldehyde is subjected to heat, and in this instance, to body heat, it sublimes, that is it forms a vapor which on cooling returns to solid state, thereby insuring a minimum loss of medicament when the pad is not in use. Thus, when the pad is not in use the paraformaldehyde does not receive the body heat and therefore there` can be no sublimation, and with no sublimation vapor cannot escape. If desired, the use of menthol may beresorted to because of its universally recognized cooling and soothing effect on the skin surface.

In connection with the above mentioned substances, boric acid is used as a reducing agent to regulate the strength of the paraformaldehyde and menthol, aside from which, in itself, Apossesses decided and proven antiseptic propertiesv and is used in deodorizing fetid sweating.

The pad I2 is cut by a die and during the cutting operation, the die compresses the marginal edges of the layers I4 so as to produce a substantially beveled unitary edge upon the pad and imparts thereto the appearance of a single layer of material. These compressed edges are designated by the numeral I5 and serve to seal the layers of gossamer like sheets entirely `around 'the marginal edge. This sealing of the edges creates of the pad in its entirety a completely housed depository for the sublime deodorant substancel.

Prior to the die cutting of .the pad, portions of the pad are compressed from opposite sides as at I'I, these compressed portions extending at spaced intervals along the length and breadth of the pad. The compressed portions I1 serve to bind the compressed layers of material together to prevent shifting of the layers in manufacture and during'use by the wearer. The comv pressed vportions also strengtheny the structure of the pad i2 and nx the medicament to insure its permanentl substantially even distribution and lessen its sifting through the layers of material and over the edges of the pad body.

As a practical matten/the compressed portions, or indentations II may be formed by passing a Yseries of superposed sheets wherein the medicament is housed through suitable rollers having a knurled, iluted or other suitable structure, which will serveto compress or indent-the sheets as desired.

The outer covering I3 constitutes a single length of. at tubular knitted fabric, which may or may not be treated with rubber, of a normal width less than the minimum width portion of the pad I2 as illustrated in Figure 4 of the drawing. The material from which this covering is constructed is loosely knitted to provide suiiicient elasticity to permit distension of the same when the pad I2 and its base II are inserted into the covering through one end thereof whereby the covering will contract and closely adhere to the opposite sides and marginal edges of the pad and base. After insertion of the pad I2 and the `base II, the ends 23 and 24 of the elastic `fabric taut in opposite directions, whether or not treated with rubber. This operation causes the fabric covering to snugly conform to the `opposite sides and marginal edges of the pad and base. Figure 5 of the drawing illustrates the pad and base after its insertion into the covering I3 and after such insertion the outer covering, while still taut, is stitched to the ends of the pad and base as at I8. After stitching the covering, pad and base, at the heel and toe, the outer extending ends 28 and 24 of the length of material are cut away, it being appreciated that the length of the outer coveringmust be at least equal to the length of the pad.

After the covering has been applied to the pad and base inl the manner just described, these parts are secured together by overedge stitching I9 which extends .entirely around the marginal edge of the article.

In practice, the deodorant foot pads are sold in pairs and inserted into the shoes of a wearer,

and in addition to the main purpose of deodorizing the odors of the feet, the pads serve as a soft yinsole which will diminish the tenderness of the fect a chemical action in the sublime deodorant causing vapors to be released from the pad, it

being understood that both the body 'of the pad and the covering are of porous substances. Thus,

objectionable odors, known as bromidosis, will be deodorized by the deodorant, aromatic and antiseptic v aporsl emanating from the pad.

In Figure of the drawing, a slightly modified form is sho wherein the ends of the article are dipped in lat x are inserted 'nto the tubular covering I3. 'I'he latex seal is esignated by the numeral 20 and is employed i lieu of the stitchingsl8 and I 9 hereinbefore described. The marginal `edge stitching mayI be dispensed with in this type of construction.

In Figure 9 f the drawing, a further modified construction I2 of pad I2 is shown, the same being constructed f llayers of gossamer like cellulose material, the la ers being secured together by cross stitchingv oquilting 2l, which creates of the pad in its en irety a completely housed depository for the sublime deodorant substance I8; strengthens the pad'structure; xes the medicament to insure its permanent substantially even distribution and lessens its sifting between the layers of gossamer-like material.

In Figure 1o of the drawing, a stm further modified form is shown wherein stitching 22 exafter the pad I2 and the base II alencon tends about the marginal edge of the pad I2"l to secure the layers of gossamer like cellulose material together in lieu of the compressed edges I5 shown in the preferred embodiment.

Although we have shown and described the ends of the covering i3 as being stitched as at l and as being secured by latex at 20, other modlcations may be resorted to if desired, such as basting at the heel and toe, and over edge stitching at the heel and toe only. v While we have shown and described what we consider to be the most practical embodiments of our invention, we wish it to be understood that any changes as .come within the scope of the appended claims may be resorted to if desired;
